Storage cart providing item storage verification

ABSTRACT

Examples provide an item storage cart for verifying correct item placement into containers on the item storage cart. A cart manager component outputs planogram data identifying a location of a selected item. Weight data generated by one or more weight sensors associated with the set of item storage containers is analyzed to verify whether a correct item is placed in a given storage container on the cart and/or verify a selected item is placed into a correct storage container. The cart manager component determines if an unselected item is removed from a storage container and/or if an unselected item is added to a storage container. A notification is output if an incorrect item is added to a cart, an incorrect item is removed from the cart, an item is added to the wrong container or removed from the wrong container.

BACKGROUND

When stocking or replenishing items on a shelf, a person frequentlyutilizes a cart or rolling bin to transport the items being stocked ontothe shelf A cart may also be used to hold items removed from a shelf orother display for grocery order fulfillment. The cart may includemultiple different bins or totes used to separate different types ofitems or to fulfill different orders. For example, but withoutlimitation, items for a first order may be stored in a first bin anditems to fulfill a second order may be stored in a second bin on thecart. In another example, one bin may be utilized to store cold itemsand another bin may be used to store non-perishable items. However, ifthere are more than one or two bins, the picker may have difficultydetermining which item goes into which bin. This may result in itemsbeing placed in the incorrect bin by mistake. Moreover, the personfrequently has difficulty locating items which are to be added to one ormore of the bins on the cart. This manual process is inefficient andtime-consuming.

SUMMARY

Some examples provide an item storage cart. The cart includes a controldevice comprising a memory communicatively coupled to at least oneprocessor. A user interface component outputs a location of a selecteditem within an item selection area. The selected item is identified forplacement within a first storage container on the storage cart. The cartincludes a housing support member connected to a portion of a basemember. The housing support member includes a set of storage containerhousings on three vertical levels configured to support a set of sixstorage containers. Each vertical level includes a pair of containerhousings. The set of storage container housings includes a firstcontainer housing at least partially enclosing the first storagecontainer. The first container housing includes an extendable guide thatextends to move the first storage container from a closed configurationinto an open configuration. In the open configuration, the user is ableto access an interior portion of the first storage container. A secondcontainer housing in the set of storage container housings encloses asecond storage container. The second storage container includes a secondextendable guide which holds the second storage container in the closedconfiguration while in a retracted state. The closed configurationpreventing user access to an aperture associated with an interior of thesecond storage container. A set of one or more weight sensors isassociated with the set of container housings. The set of weight sensorsgenerates weight data associated with the first storage container andthe second storage container. A cart manager component analyzes theweight data with item data associated with the selected item to verifythe selected item is placed into the first storage container. The itemdata includes a predetermined weight of the selected item.

Other examples provide a rolling storage cart. The rolling storage cartincludes a base member having a set of one or more wheels. A housingsupport member is connected to the base member. The housing supportmember includes a set of storage container support members supporting aset of storage containers. The set of storage containers includes afirst storage container and a second storage container. A first storagecontainer support member includes a first locking mechanism removablysecuring the first storage container to the first storage containersupport member in a closed configuration. A second storage containersupport member includes a second locking mechanism removably securingthe second storage container to the second storage container supportmember in the closed configuration. A cart manager component identifiesa selected item for addition to the first storage container or removalfrom the first storage container. The cart manager component triggersdisengagement of the first locking mechanism to release the firststorage container while engaging the second locking mechanism to preventopening of the second storage container. A first set of sensor devicesassociated with the first storage container generates first sensor dataassociated with a first set of items within the first storage container.The cart manager component analyzes the first sensor data to verify theselected item is added to the first storage container or removed fromthe first storage container.

Still other examples provide a computer-implemented method for verifyingcontents of storage containers on a cart. Scan data identifying an itemfor placement into at least one storage container on an item storagecart is received from a scanner device. A cart manager componentidentifies a selected storage container assigned to the identified item.A user interface component outputs a graphical representation of alocation of the identified item on an item display within an itemselection area. A locking mechanism associated with the selected storagecontainer releases to enable user access to at least a portion of anaperture associated with the selected storage container. An analysiscomponent analyzes weight data generated by a weight sensor associatedwith at least the selected storage container to verify the identifieditem is placed into the selected storage container. The lockingmechanism re-engages if the weight data indicates a weight incrementassociated with the selected storage container corresponds with apredetermined weight of the identified item. The user interface deviceoutputs a notification indicating failure to detect placement of theidentified item into the selected storage container if a weightincrement detected by the weight sensor fails to correspond to apredetermined weight of the identified item.

As such,any and all statements or other indications as to what a particularfigure depicts, what a particular element or entity in a particularfigure is or has, and any and all similar statements, that may inisolation and out of context be read as absolute and therefore limiting,may only properly be read as being constructively preceded by a clausesuch as “In at least some examples, . . . ” For brevity and clarity ofpresentation, this implied leading clause is not repeated ad nauseum.

Referring to the figures, examples of the disclosure enable a mobileitem storage cart for verifying contents of containers on the cart. Insome examples, the item storage cart includes a cart manager componentwhich analyzes sensor data generated by sensor devices on the cart toverify correct items are placed into correct containers on the cart. Ifan incorrect item is placed on the cart, the cart outputs a notificationor an alert to a user. Likewise, if the correct item is placed into thewrong container on the cart, the cart outputs a notification or analert. This enables verification of container contents andreduction/prevention of stocking and picking errors.

Referring again to FIG. 1, an exemplary block diagram illustrates asystem 100 for verifying contents of containers on an item storage cart.In the example of FIG. 1, the item storage cart 102 represents any cartfor storing items. The item storage cart 102 may be a stocking cart forstoring items used to stock a shelf or other item display. The itemstorage cart 102 may be a pick cart used to store items removed from ashelf or other item display for grocery order fulfillment, pallet build,or other picking task.

An item display in the set of item displays may include shelves,side-counters, end-cap displays, refrigerated displays, freezercompartments, gondola shelves, bins, or any other item displayassociated with one or more aisle(s) 206 or other areas within an itemselection area in a retail environment. An item selection area is astore or other retail space in which one or more items are displayed. Anitem selection area may include an entire store or an area/departmentwithin a store. An item display is sometimes referred to as a modulardisplay, display shelf, end-cap display, counter display or other areain a store in which items in the same or similar category arestored/displayed for viewing by shoppers.

The item storage cart 102 executes computer-executable instructions 104(e.g., as application programs, operating system functionality, or both)to implement the operations and functionality associated with the itemstorage cart 102. In some examples, the item storage cart 102 has atleast one processor 106 and a memory 108. The item storage cart 102 mayalso include a user interface component 110.

The processor 106 includes any quantity of processing units and isprogrammed to execute the computer-executable instructions 104. Thecomputer-executable instructions 104 may be performed by the processor106 or by multiple processors within the item storage cart 102 orperformed by a processor external to the item storage cart 102. In someexamples, the processor 106 is programmed to execute instructions suchas those illustrated in the figures (e.g., FIG. 13 and FIG. 14).

The item storage cart 102 further has one or more computer-readablemedia such as the memory 108. The memory 108 includes any quantity ofmedia associated with or accessible by the item storage cart 102. Thememory 108 may be internal to the item storage cart 102 (as shown inFIG. 1), external to the computing device (not shown), or both (notshown).

The memory 108 stores data, such as one or more applications. Theapplications, when executed by the processor 106, operate to performfunctionality on the item storage cart 102. The applications maycommunicate with counterpart applications or services such as webservices accessible via a network 112. For example, the applications mayrepresent downloaded client-side applications that correspond toserver-side services executing in a cloud.

In other examples, the user interface component 110 includes a graphicscard for displaying data to the user and receiving data from the user.The user interface component 110 may also include computer-executableinstructions (e.g., a driver) for operating the graphics card. Further,the user interface component 110 may include a display (e.g., a touchscreen display or natural user interface) and/or computer-executableinstructions (e.g., a driver) for operating the display. The userinterface component 110 may also include one or more of the following toprovide data to the user or receive data from the user: speakers, asound card, a camera, a microphone, a vibration motor, one or moreaccelerometers, a BLUETOOTH® brand communication module, globalpositioning system (GPS) hardware, and a photoreceptive light sensor.

The network 112 is implemented by one or more physical networkcomponents, such as, but without limitation, routers, switches, networkinterface cards (NICs), and other network devices. The network 112 maybe any type of network for enabling communications with remote computingdevices, such as, but not limited to, a local area network (LAN), asubnet, a wide area network (WAN), a wireless (Wi-Fi) network, or anyother type of network. In this example, the network 112 is a WAN, suchas the Internet. However, in other examples, the network 112 may be alocal or private LAN.

In some examples, the system 100 optionally includes a communicationsinterface component 114. The communications interface component 114includes a network interface card and/or computer-executableinstructions (e.g., a driver) for operating the network interface card.Communication between the item storage cart 102 and other devices, suchas but not limited to the data storage device 115 and/or a remotecomputing device 116, may occur using any protocol or mechanism over anywired or wireless connection. In some examples, the communicationsinterface component 114 is operable with short range communicationtechnologies such as by using near-field communication (NFC) tags.

The computing device 116 represents any device executingcomputer-executable instructions. The computing device 116 may include amobile computing device or any other portable device. In some examples,the computing device 116 includes a mobile telephone, laptop, tablet,computing pad, netbook, gaming device, and/or portable media player. Thecomputing device 116 may also include fewer portable devices such asservers, desktop personal computers, kiosks, or tabletop devices.Additionally, the computing device 116 may represent a group ofprocessing units or other computing devices. In some examples, thecomputing device 116 has at least one processor and a memory. Thecomputing device 116 may also include a user interface component.

The data storage device 115 may include one or more different types ofdata storage devices, such as, for example, one or more rotating disksdrives, one or more solid state drives (SSDs), and/or any other type ofdata storage device. The data storage device 115 in some non-limitingexamples includes a redundant array of independent disks (RAID) array.In other examples, the data storage device 115 includes a database.

The data storage device 115 in this example is located remotely from theitem storage cart 102. In other examples, the data storage device 115may be included within the item storage cart 102 or associated with thecomputing device 116. In other examples, the data storage device 115 maybe a remote data store, such as, but not limited to, a data storage in aremote data center and/or a cloud storage.

The data storage device 115 stores data utilized for managing the itemstorage cart and verifying contents of containers on the item storagecart, such as, but not limited to, item data 118 associated with one ormore items, such as the set of items 120 in the set of storagecontainers 122. Item data 118 may include, without limitation, itemweight data, item image data, item barcode data, item size data, itemlocation on a display or other shelf, etc.

The set of storage containers 122 is a set of one or more containers forholding or storing one or more items. A storage container in the set ofstorage containers 122 may include, without limitation, a tote, abasket, a box, a crate, or any other type of container. In somenon-limiting examples, the set of storage containers 122 includes sixtotes.

The memory 108 in some examples stores one or more computer-executablecomponents, such as, but not limited to, a cart manager component 124.The cart manager component 124 analyzes sensor data received from a setof sensor devices to identify a selected item. In some examples, thecart manager component 124 analyzes scan data generated by a barcodescanner scanning a barcode or other item identifier on the selected itemto identify the item. If the item is being added to the cart, the cartmanager component identifies a container on the cart forplacement/storage of the item. The container may be selected based on aper-order basis.

The user interface component 110 in some examples outputs a location ofa selected item within an item selection area identified for placementwithin a first storage container on the storage cart. For example, if auser is picking items to fulfill two different grocery orders and thefirst order includes a gallon of milk, the cart manager component 124analyzes scan data generated when the user scans the gallon of milk. Thecart manager component identifies the container linked to the firstorder and assigns the gallon of milk to that container.

In other examples, the cart manager component 124 analyzes sensor datagenerated by a sensor device associated with a selected storagecontainer to determine whether the user slides the selected storagecontainer open or otherwise accesses an interior portion of the selectedstorage container. For example, the sensor device may be implemented asa pressure sensor, a light sensor or other sensor device capable ofdetecting movement of the container as the storage container slidesoutward to provide access to the interior of the container.

The cart manager component 124 in still other examples analyzes weightdata generated by one or more weight sensors associated with eachstorage container on the item storage cart 102. The weight sensorsdetect increases in weight (weight increment) and/or weight decrease(weight decrement) associated with a selected container. The cartmanager component 124 compares the predetermined/known weights of one ormore items, known weight of the empty container and/or other item data118 to determine whether a selected item (scanned item) is added to agiven storage container.

In still other examples, the cart manager component 124 analyzes weightdata to detect unauthorized removal of items from the cart and/orunauthorized addition of items to the cart. For example, if a thirdparty removes one or more items from one or more of the storagecontainers on the cart, the cart manager component 124 detects thedecrease in weight for the one or more storage containers. The cartmanager component 124 sends out a notification or emits an alert 115 tonotify a user of the removal of the item(s) via the communicationsinterface component 114 in some examples. In other examples, the alert115 is output to the user via the user interface component 110.

Likewise, the cart manager component 124 analyzes weight data generatedby sensor devices on the set of storage containers 122 using item data118 to determine whether an incorrect item or an incorrect number (wrongquantity) of items is added to any of the storage containers. If anincorrect item is added, the cart manager component 124 sends out anotification or emits the alert 115 to notify a user of the addition ofthe incorrect item and/or incorrect number of items.

The alert 115 in some examples is an audible alert, such as, but notlimited to, a beeping, a verbal alert (recorded message), an alarm, orother sound. In other examples, the alert 115 is a visual alert, suchas, but not limited to, a text message, a light, a video display, agraphical image, or other visual notification. The alert 115 optionallyincludes a haptic alert, such as a vibration or other haptic output. Instill other examples, the alert 115 is a combination of a visual alert,an audible alert and/or a haptic alert. For example, the alert 115 inone example is a blinking light accompanied by an audible beeping soundand a vibration output by a user interface device. In another example,the alert 115 is a text notification accompanied by an audible voicereading the text aloud.

The item storage cart 102 in this non-limiting example is a cartincluding a set of wheels 126 which is pushed or pulled by a user. Inother examples, the item storage cart 102 is a self-propelled/motorizedcart. In these examples, the item storage cart includes a brakingmechanism 128 and a propulsion mechanism 130 coupled to the set ofwheels 126. The propulsion mechanism 130 includes a power source, suchas, but not limited to, an electric battery, solar panels and/or anelectric motor. A navigation component 132 provides navigational data134 to the propulsion mechanism 130 to enable the cart to moveautonomously from a first location to a second location viaself-propulsion.

In one non-limiting example, if the cart manager component detects aweight increase (variance) outside preconfigured threshold, the brakingmechanism 128 automatically stops/brakes. In other words, if a weightthreshold is exceeded, the cart automatically places itself into park(park mode) stopping/preventing the cart from moving until the weight onthe cart is reduced/falls below the maximum weight limit. This preventsdamage to the cart and/or prevents potential risk to operators of thecart. For example, if a child or animal jumps on the cart, the weightaddition due to the child or animal resulting in the cargo weightexceeding the maximum weight threshold results in the braking mechanismapplying the brakes or the cart manager component otherwise shuttingdown the propulsion system to stop autonomous movement of cart.

FIG. 2 is an exemplary block diagram illustrating an item selection area200. The item selection area 200 may include an interior portion of astore, an exterior portion of a store, a portion of a store, an areawithin a store, a department, a storage area and/or any other retailenvironment. For example, an item selection area may include a grocerystore, a warehouse, a distribution center, a garden center, a dairysection, a paper goods aisle, etc.

The item selection area 200 includes a plurality of items 202 associatedwith one or more display areas in a set of item displays 204. Theplurality of items 202 includes two or more items.

In some examples, the item storage cart 102 includes a set of extendableguides 318 configured to at least partially extend or push one or morestorage container from a closed configuration into an openconfiguration. In these examples, each storage container is removablyconnected to an extendable guide. When the extendable guide is fullyretracted, the storage container is in a closed configuration in whichthe interior portion of the container is inaccessible. When theextendable guide extends horizontally, it pushes or slides the storagecontainer outward into an open configuration enabling user access to atleast a portion of an interior of the storage container.

The item storage cart 102 may include a set of support members 320connected to the housing support member 308. Each storage container inthe set of storage containers 122 rests on at least one support memberin the set of support members. The support members may be arrangedvertically in one or more levels. In this non-limiting examples, thesupport members include a set of three support members for supportingone or more containers on three levels.

A set of locking mechanisms 322 may be optionally included in otherexamples. In these examples, each support member or storage containerhousing includes a locking mechanism to lock a storage container in theclosed configuration. The locking mechanism may include a lock, a latch,a bar, a folding arm, an extending arm, or other mechanism holding thestorage container in the closed configuration. When the lockingmechanism is released, the storage container is free to be pulled out orslide out to enable user access to the interior of the container. Whenthe locking mechanism associated with a selected storage container isengaged, the selected storage container is incapable of being pulledopen, sliding out, or otherwise moving into the open configuration.

The item storage cart 102 includes a set of one or more sensor devices324. The set of sensor devices may include a set of weight sensorsassociated with the set of container housings. The set of weight sensorsincludes a first weight sensor generating weight data associated witheach storage container in the set of storage containers 122. The cartmanager component analyzes the weight data with item data associatedwith the selected item, including a predetermined weight of the selecteditem, to verify correct items are placed into the correct storagecontainers and/or verify correct items are removed from the correctcontainers.

FIG. 4 is an exemplary block diagram illustrating a rolling item storagecart. The item storage cart 102 in this example includes the housingsupport member 308 connected to the portion of the base member 310. Thebase member 310 includes the set of wheels 126 giving the cart mobilityenabling the item storage cart 102 to function as a rolling item storagecart.

The housing support member 308 in some non-limiting examples includes aset of six storage container housings on three vertical levelsconfigured to support a set of six storage containers. Each verticallevel in this example includes a pair of container housings.

In this example, the first level includes a first storage container 410associated with a first support member 412 and a second storagecontainer 414 on a second support member 416. The second level 418includes a third storage container on a third support member 422 and afourth storage container 424 on a fourth support member 426. The thirdlevel 428 includes a fifth storage container 430 on a fifth supportmember 432 and a sixth storage container 434 on a sixth support member436.

The support member 432, support member 422, support member 412, supportmember 416, support member 426, and/or the support member 436 aresupport members in a set of members, such as, but not limited to, theset of support members 320 in FIG. 3. The storage container 430, storagecontainer 420, storage container 410, storage container 434, storagecontainer 424 and/or storage container 414 are storage containers in aset, such as, but not limited to, the set of storage containers 122 inFIG. 1 and FIG. 3.

FIG. 5 is an exemplary block diagram illustrating a set of storagecontainers on the item storage cart 102 in a closed configuration. Theitem storage cart 102 in some examples includes the set of storagecontainer housings 314 on three vertical levels configured to support aset of six storage containers. In this example, all the containers onthe cart are shown in a closed configuration.

A first container housing 504 in this example partially encloses a firststorage container 506 in a closed configuration. The first containerhousing 504 may entirely enclose the first storage container orpartially enclose the first storage container. In this example, thefirst container housing 504 includes a bottom member, two side membersand a top member with two open sides to partially enclose the firststorage container while enabling the first storage container to slidehorizontally outward through either of the open ends.

A second container housing 510 in the set of encloses a portion of asecond storage container 508 in a closed configuration. A thirdcontainer housing 514 encloses a third storage container 512 in a closedconfiguration. The third container housing may entirely enclose thethird storage container or partially enclose the third storagecontainer.

The item storage cart 102 includes a user interface device, such as, butnot limited to, a display device 516. The display device 516outputs/displays a location of an item on a shelf, a location of an itemon the cart, a planogram/graphical representation of a planogram showinga location of an item on an item display within the item selection area,or other information of potential interest to a user operating the itemstorage cart 102.

The display device 516 optionally outputs a notification or alarmalerting the user that an incorrect item has been placed inside acontainer and/or an item has been placed inside the incorrect container.The notification and/or alarm may also be utilized to notify the userthat the incorrect number of instances of an item have been placedinside a container on the cart or removed from a container on the cart.For example, if the user is supposed to place two cans of beans into thethird container 512, the cart manager component analyzes weight data todetermine how many cans of beans are added to the cart. If only a singlecan of beans is added, or more than two cans of beans are added to thecontainer, the system outputs a notification or alert on the displaydevice informing the user that an incorrect number of instances of theselected item have been added.

The item storage cart 102 in this example includes two item storagecontainers supported on each of the three levels. For example, thestorage container 518 in the container housing 520 and the storagecontainer 506 are supported on support member 530 at the first level.The storage container 522 in the container housing 524 and the storagecontainer 508 are supported on support member 532 at the second level.The storage container 526 in the container housing 528 and the storagecontainer 5124 are supported on support member 52 at the third level.

The storage containers are supported on the base member 310. The set ofwheels 126 are connected to an underside of the base member 310. The setof wheels enable the item storage cart to roll or otherwise move fromone location to another.

In the example shown in FIG. 5, the item storage cart 102 includes sixstorage containers (totes) stacked on three vertical levels on the cart.However, the examples are not limited to this configuration. The itemstorage cart optionally includes any number of totes on any number oflevels. For example, the item storage cart in one example includes eightitem storage containers (totes) on four vertical levels. In anotherexample, the item storage cart includes ten item storage containers onfive vertical levels.

Likewise, in the example shown in FIG. 5, there are two item storagecontainers supported on each vertical level. However, the examples arenot limited to two item storage containers per level. In other examples,each vertical level on the cart optionally supports a single itemstorage container, as well as three or more item storage containers. Inone example, the item storage cart includes three item storagecontainers on each level. In another example, the item storage cartincludes four item storage carts on each level.

FIG. 6 is an exemplary block diagram illustrating a set of storagecontainers on the item storage cart 102 in an open configuration. Theset of storage containers on the item storage cart 102 in the exampleincludes eight item storage containers arranged on four vertical levels.In this example, the first level 602 from the top includes storagecontainer 604 and storage container 606. The second level 608 includesstorage container 610 and storage container 612. The third level 614includes storage container 616 and storage container 618. The fourthlevel 620 includes storage container 622 and storage container 624.

When the storage container 618 is pulled or pushed through the open end,an aperture 626 at the top of the first storage container is exposed toenable access to an interior portion of the storage container 618.

In this example, the set of storage containers includes storagecontainer 616 and storage container 618 supported on the support member532. The support member 532 is an extendable guide, which is fullyextended in FIG. 6 to place the storage container 618 into the openconfiguration.

In this example, the storage container 618 is supported on a fullyretracted guide holding the storage container in the open configurationenabling access to an interior storage area within the storage containerwhile the remaining containers are held in the closed configurationpreventing access to the interior of those remaining containers. Inother words, storage container 618 in FIG. 6 is shown in an openconfiguration with the support member fully extended. The other storagecontainers in the set of storage containers on the item storage cartremain in the closed configuration while one item storage container isat least partially slide out of the container housing on the cart(open).

In some examples, when any storage container is in an openconfiguration, the remaining storage containers are locked into a closedconfiguration. This prevents items from being placed into the incorrectcontainer. It also prevents one or more items from being removed from astorage container without authorization/approval.

FIG. 7 is an exemplary block diagram illustrating a locking mechanism702 associated with a storage container 704 on an item storage cart in aclosed configuration. The locking mechanism 704 is a device to hold astorage container in a closed configuration, such as, but not limitedto, one or more locking mechanisms in the set of locking mechanisms 322in FIG. 3.

The locking mechanism in this example is an arm or flap which is raisedto lock the storage container 704 in the locked configuration. Thelocking mechanism may be attached to a support member or a containerhousing. In this example, the locking mechanism 702 is connected to asupport member 706 connected to a housing support member 708.

FIG. 8 is an exemplary block diagram illustrating the locking mechanism802 associated with a storage container on an item storage cart in anopen configuration. The locking mechanism is a device to hold a storagecontainer in a closed configuration, such as, but not limited to, one ormore locking mechanisms in the set of locking mechanisms 322 in FIG. 3.

The locking mechanism 802 in this example is an arm or flap which islowered to unlock or release the storage container enabling a user toadd items to the container. The locking mechanism 802 may be attached toa support member 804 or a container housing. In this example, thesupport member 804 connects to a housing support member 806.

In some examples, the support member 804 is on a slight downward slope.In these examples, when the locking mechanism 802 disengages, gravitypulls the cart down the sloping support member enabling the container toautomatically slide open without human intervention. In other examples,a guide arm or other mechanism pushes the container outward into theopen configuration. In yet other examples, the user pulls the storagecontainer out to access the interior of the container. When the user isfinished, the user pushes the container backward until the lockingmechanism engages or re-engages to hold the container in the closedconfiguration/prevent the container from sliding out.

In another non-limiting example, the user pushes the container backwardand manually re-engages the locking mechanism to hold the storagecontainer in the closed configuration. In these examples, the lockingmechanism may include a latch, a bar, a tab, a lip, a clip or any otherdevice for holding the storage container in the closed configuration.

FIG. 9 is an exemplary block diagram illustrating a retracted guide 900associated with a storage container 902 in a closed configuration. Theretracted guide 900 in this example connects to a housing support member904. The guide is an extendable guide configured to extend outward whena storage container is opened and retract inward when the storagecontainer is pushed back into the storage container housing on the cart.

FIG. 10 is an exemplary block diagram illustrating an extended guide1000 associated with a storage container 1002 in an open configuration.The extended guide 1000 in this example connects to a housing supportmember 1004.

In one example, the guide is connected to a mechanism or motor whichautomatically moves the storage container 1002 from the closedconfiguration to the open configuration for pick/place. In the openconfiguration, an interior 1006 portion of the storage container 1002 isaccessible to the user. In other words, items may be added to theinterior 1006 via an aperture/opening at the top of the storagecontainer when the storage container is pulled out in the openconfiguration.

In this example, the guide retracts automatically when the pick orplacement is complete for improved safety and efficiency. The automaticretraction further prevents additional incorrect items from being addedto a storage container after a correct item has been placed into it orremoved from it. The guide further prevents the storage container frombeing pulled too far out or being removed from the cart prior tocompletion of the pick/stock.

The guide in some examples is implemented as a bar, a track, or abracket for partially supporting an edge or other portion of a storagecontainer as the storage container is partially pulled out of thestorage container housing to place the container in the openconfiguration enabling access to the container's interior contents. Inother examples, the guide is a pair of bars, tracks or bracketsconfigured to support and guide the storage container as it is partiallypulled out the storage container housing. The guide also supports anddirects the storage container back into proper alignment within thestorage container housing as the storage container is re-inserted orotherwise pushed back into the storage container housing to return thecontainer to the closed configuration.

FIG. 11 is an exemplary block diagram illustrating a set of sensordevices 324. The set of sensor devices 324 includes one or more sensordevices for verifying contents of containers on a cart. The set ofsensor devices 324 includes a set of one or more weight sensors 1102,such as, but not limited to, scales for generating weight data 1104. Theweight data includes weight changes associated with an increase ordecrease in weight associated with each storage container.

The set of sensor devices 324 may optionally include a set of one ormore image capture devices 1106 generating image data 1108. The imagecapture devices may include cameras or infrared (IR) camera.

A set of one or more pressure sensors 1112 may optionally be included.The set of pressure sensors 1112 generate pressure data 1114 associatedwith each storage container on the cart. The pressure data 1114 isanalyzed to determine whether a selected storage container is in an openconfiguration or a closed configuration.

The set of scanner devices 1116 optionally includes devices for scanningan item identifier, such as, but not limited to, a universal productcode (UPC) code, a barcode, a matrix barcode, a radio frequencyidentification (RFID) code, a quick response (QR) code, or any othercode. The set of scanner devices generates scan data 1118 associatedwith an item scanned by the user. The user in some examples scans aselected item prior to placing the item into a container on the cart.The cart manager component utilizes the scan data to determine whichcontainer the scanned item should be placed into.

The scanner device(s) may also be used to scan cases of items instead ofscanning individual items. In these examples, the user scans a barcodeor other identifier on a case holding one or more items. The user placesthe case into the appropriate storage container on the cart. In yetanother examples, the scanner devices may be used to scan a barcode,electronic shelf label (ESL), QR code, RFID tag or other identifier on astorage container to identify a particular storage container. Thescanner devices may include an RFID tag reader, a QR code reader, a UPCcode reader, a barcode reader, a matrix barcode reader, etc.

In some examples, the set of weight sensors are integrated into platformtrays/support members under each storage container. The weight sensorsmay be tied into the processing unit to detect incremented/decrementedweight levels. The cart manager component analyzes the weight data todetermine the location of the weight sensor generating the weight datato identify which storage container had an item removed from it or addedto it. The weight sensors also allow the cart manager component todetermine where an identified storage container has been placed on thecart and/or determine whether a storage container is present at aparticular location (level/position) on the cart.

In other examples, the set of sensor devices may include light sensors,proximity sensors, photoelectric cells and/or any other sensor devicesfor detecting location and position of items on the cart. In oneexample, a photocell beam pointing up from a support member (platform)in front of a storage container (tote/bin) is broken when the storagecontainer is moved/slides out. The sensor data indicating the beam isbroken confirms that the storage container is removed/pulled. If thewrong container is pulled, the system outputs a notification/alertnotifying a user that the wrong bin is pulled.

FIG. 12 is an exemplary block diagram illustrating a cart managercomponent 124. The cart manager component 124 includes an analysiscomponent 1202. The analysis component 1202 analyzes sensor data 1204,such as, but not limited to, scan data 1118 generated by a scannerdevice and/or weight data 1208 generated by a weight sensor. The sensordata 1204 in other non-limiting examples may include pressure datagenerated by a pressure sensor, temperature data generated by athermometer or temperature sensor, humidity data generated by ahygrometer, image data generated by a camera, infrared data generated byan infrared sensor, motion data generated by a motion sensor, locationdata generated by a geolocation sensor, light data generated by a lightsensor, or any other type of sensor data generated by one or more sensordevices. A geolocation sensor is a sensor for detecting a location, suchas, but not limited to, a beacon transmitter, a beacon receiver, aglobal positioning satellite (GPS) receiver, a Wi-Fi device, or anyother device for determining a location of an item.

The analysis component 1202 analyzes the sensor data 1204 to identify alocation 1210 of an item on an item display or other shelf in the itemselection area. The location may include an aisle number 1212, a sectionnumber 1214 and/or an item display location identifier (ID) 1216.

The analysis component 1202 analyzes sensor data 1204 to determine anamount of weight increment 1218 when an item is added to a container onthe cart and/or an amount of weight decrement 1220 when an item isremoved from a container on the cart.

In other examples, the analysis component 1202 analyzes sensor data 1204to generate location data 1222 for the location of a selected item,including planogram data 1224. The planogram data may include agraphical representation 1226 of a display or portion of an item displaywhere an item to be picked is located. The planogram data displayed onthe item storage cart in one example includes a picture of a modulewithin a planogram of a store to guide the user to the module. Theplanogram display adjusts/updates to drill down the picture of the itemlocation on the module to provide the user with a visual of the correctitem to select. In an item stocking scenario, the planogram shows agraphical image of the item display to be stocked. The modular-specificimage is shown on the display, with a highlighted box around the item tobe picked. The display updates to ensure the user pulls items from thecorrect storage location (bin/tote) at that location in the store tostock shelves. This reduces the amount of time users spend at shelf edgesearching for items to pick. It is time savings for picking/stocking.The planogram may also be provided to reduce time expended by customerssearching for items while shopping.

The planogram data may be output to the user in other examples via adigital screen or other display on the cart. The display screen showsthe appropriate planogram by using the pick path in graphics interchangeformat (GIF). In this example, no location services are necessary. Thepicking service directs the geographic path. The planogram is built intoROC store map.

In one example, a user scans each item as the item is picked and placedinto the cart. With each pick, there is a scan confirmation. Thereforethe system knows to move on to the next item on the list, even if onsame modular. If the pick path has 1% milk, chocolate milk, and yogurton the same modular item display, the system triggers item picking alongthat path without permitting/allowing for picking items out of order.

If an item is unavailable, the user may utilize the user interfacecomponent to report/select “item not found” and initiate an exceptionflow. The user may also identify/flag planograms errors via the userinterface device. Types of issues that might be flagged include itemsnot present in the location indicated on the planogram data, itemslocated on a different/wrong shelf, items located in a different/wrongposition than shown on the planogram, and/or a planogram that iscompletely incorrect for that location. An exception flow is theninitiated.

In a non-limiting scenario, when a user notices something is off in thepicking process, the user clicks a “flag” button on the user interface(UI). The button may be a physical button or an icon on a graphical userinterface. The user provides additional feedback indicating whether theproblem is with the modular location or aisle location. The UI opens upand the user clicks/selects the modular/aisle location issue. The listoptions/problem details associated with the planogram data may includespecifying whether an item label is in the wrong spot, whether an itemlabel is missing from the modular/item display, whether the aislelocation for the item is incorrect/wrong and/or whether the locationarea/section provided for the item is wrong.

In another non-limiting example, if the number of “flags” for planogramdata/location data associated with a selected item reaches a thresholdnumber, the system alerts a manager or other personnel to address theissue/update the planogram and/or location data associated with theitem. Likewise, real-time data from cameras, robotic sensor devices(autonomous robotic camera devices) and/or data feeds may also beutilized to update/modify the planogram data/location data for an itemif the number of location data error flags reaches the threshold level.

In still another example, the planogram data may be generated usingreal-time or near-real-time image data generated by robotic rovingcamera device(s) autonomously moving throughout the item selection area.The image data is utilized to update the planogram data with real-timeimage data more accurately showing locations of items, positions ofitems on displays, numbers of items available, etc. Generic planogramwould be a fallback if no Robotic roving camera images are available.

The image data generated by the roving robotic camera devices may beused in other examples to identify the location of an item which is notin its assigned item display area. If an item cannot be found on itsnormal display space, image data from robotic cameras are retrieved tofind the item(s). If a user is picking an item that's supposed to be inan aisle display identified as “J-11”, image data may be used todetermine the item is actually (incorrectly) located in “K-12”.

The robotic camera devices in other examples may communicate with theitem storage carts and/or a remote server to update item location data.The communication between the robotic cameras and the item storage cartsystem enables validation that says if a recent scan in last “X” hoursby at least one robotic camera device, the system uses thatlocation/image data instead of the basic (proper) location planogramdata for the digital planogram display.

Item location data may be pulled down from a cloud storage or otherremote data store and utilized to update the item storage cart planogramdisplay data at the outset of the pick.

The analysis component 1202 in other examples analyzes sensor data 1204,including the weight data, to generate verification data 1236 verifyinga correct item 1228 is placed into a correct container 1230 on the cart.If the verification data 1236 indicates an incorrect item is placed intothe correct container, an incorrect number of items are placed into acontainer and/or a correct item is placed into an incorrect/wrongcontainer on the cart, the cart manger component outputs a notificationor other alert to the user.

A notification may include an identification of the item, anidentification of the container the item was placed into, anidentification of the container the item should have been placed into,and/or a location of the item on an item display. The notification/alertmay include a flashing light, audio output and/or graphical output.

The cart manager component 124 in some examples analyzes the sensor data1204 with item data 1238 to generate the location data 1222 and/or theverification data 1236. The item data 1238 may include a predeterminedweight 1240 of one or more items and/or an item ID 1242 for a selecteditem/scanned item. In one example, the cart manger component 124downloads the item data, including item descriptions and/or itemweights, from the data storage device on the cart, a remote server, acloud storage or other remote data store.

In some non-limiting examples, the cart manager component 124 includes astocking component 1244. The stocking component utilizes an itemidentification 1246 to identify a display location 1248 of theidentified item and a container ID 1250 of a container on the cart wherethe identified item should be placed.

FIG. 13 is an exemplary flow chart illustrating operation of thecomputing device to manage items on an item storage cart. The processshown in FIG. 13 may be performed by a cart manager component, executingon a smart item storage cart, such as the item storage cart 102 in FIG.1.

The process begins by determining if scan data is received at 1302. Thescan data is data generated by a scanner or other sensor device, suchas, but not limited to, the scan data 1118 in FIG. 11 and FIG. 12. Ifyes, the cart manager component analyzes the scan data to identify anitem at 1304. The cart manager component identifies a storage containerassigned to the item at 1306. The cart manager component puts theidentified storage container into an open configuration at 1308. Theopen configuration is a configuration in which an interior of thestorage container is accessible to a user, such as, but not limited to,the storage container 508 into the open configuration as shown in FIG.6.

The cart manager component analyzes sensor data at 1310 associated withthe storage containers. The sensor data is data generated by a set ofone or sensor devices, such as, but not limited to, the sensor data 1204in FIG. 12. The set of sensor devices is a set of one or more sensordevices, such as, but not limited to, the set of sensor devices 324.

The cart manager component determines if the identified item is added tothe correct container at 1312. If no, the cart manager component outputsan alert at 1316. The alert is a notification, such as the alert 115 inFIG. 1.

The cart manager component determines whether to continue at 1314. Ifyes, the cart manager component returns to 1302 and iteratively executesoperations 1302 through 1314 until a determination is made not tocontinue at 1314. The process terminates thereafter.

While the operations illustrated in FIG. 13 are performed by a computingdevice, aspects of the disclosure contemplate performance of theoperations by other entities. For example, a cloud service may performone or more of the operations.

FIG. 14 is an exemplary flow chart illustrating operation of thecomputing device to manage items on an item storage cart. The processshown in FIG. 14 may be performed by a cart manager component, executingon a smart item storage cart, such as the item storage cart 102 in FIG.1.

The process begins by outputting a location of a selected item on anitem display at 1402. The selected item is an item, such as, but notlimited to, an item in the set of items 120 in FIG. 1. The cart managercomponent releases a locking mechanism on a selected container at 1404.The locking mechanism is a device to hold a storage container in aclosed configuration, such as, but not limited to, one or more lockingmechanisms in the set of locking mechanisms 322 in FIG. 3.

The cart manager component analyzes weight data associated with thecontainer using item data at 1406. The weight data is data generated byscales or other weight sensor devices, such as, but not limited to, theweight data 1208 in FIG. 12. The cart manager component determineswhether the item is added to the selected container at 1408. If yes, thecart manager component re-engages the locking mechanism at 1410. Thecart manager component determines whether there is a next item to beadded to the cart at 1412. If yes, the cart manager component returns to1402 and iteratively executes operations 1402 through 1412 until thereare no additional items to add to the cart at 1412. The processterminates thereafter.

While the operations illustrated in FIG. 14 are performed by a computingdevice, aspects of the disclosure contemplate performance of theoperations by other entities. For example, a cloud service may performone or more of the operations.

ADDITIONAL EXAMPLES

In some examples, a modified stocking and picking cart is provided whichprovides planogram data associated with item displays as stocking andpicking aids to users. The cart is electric and includes a put-to-lightsystem for picking from shelves to fulfill orders.

In an example scenario, the cart includes storage containers stackedthree-levels high for a total of six storage containers on the cart byreducing the gap between levels. Each storage container (bin) pulls outto enable a user to add item(s) to the container or remove item(s) fromthe container. A sensor device on the container generates sensor dataindicating when a container is pulled out/opened by a user making iteasier to confirm an item was placed in the appropriate bin. In otherwords, an item cannot be placed into a container on the cart withoutmoving the cart. Therefore, a sensor device on the container detectsopening/accessing of each bin/container when items are placed into thebin or removed from the bin.

In another example, the cart includes a visual display with an interfacethat displays the shelf/bin location of an item to be picked and placedinto a container on the cart. The location display may include aplanogram or portion of a planogram graphically depicting the locationof the item/variety of the item on the shelf or other item display. Theplanogram image includes the location for the product to bepicked/stocked by highlighting or otherwise indicating the location onthe display screen

In yet other examples, each storage container on the cart includes ascale/weight sensor to confirm picks based on the weight increments whenan item is added to the container. In the case of more than one quantityof an item (multiple instances) being picked, once one of the items isscanned and placed, the scale determines the proper quantity waspicked/placed. If the user is stocking an item display with item fromthe cart, the cart manager component utilizes the weight data to verifyweight decrements correspond to correct items removed from thecontainers in stocking mode.

When a user scans an item taken off a shelf in one non-limiting example,a fixed light on the cart lights up to indicate which bin the itemshould be placed into. Each bin on the cart may correspond to adifferent order. Weight sensors detect correct or incorrect binplacement. The cart generates a notification to output to displayindicating whether the item placement is verified as correct orunverified (incorrect). If multiple items are ordered (three instancesof an item), the user scans a single item. The cart manager componentanalyzes weight sensor data to detect three iterations of that itemadded to the selected container(s).

Examples of well-known computing systems, environments, and/orconfigurations that may be suitable for use with aspects of thedisclosure include, but are not limited to, mobile computing devices,personal computers, server computers, hand-held or laptop devices,multiprocessor systems, gaming consoles, microprocessor-based systems,set top boxes, programmable consumer electronics, mobile telephones,mobile computing and/or communication devices in wearable or accessoryform factors (e.g., watches, glasses, headsets, or earphones), networkPCs, minicomputers, mainframe computers, distributed computingenvironments that include any of the above systems or devices, and thelike. Such systems or devices may accept input from the user in any way,including from input devices such as a keyboard or pointing device, viagesture input, proximity input (such as by hovering), and/or via voiceinput.

Examples of the disclosure may be described in the general context ofcomputer-executable instructions, such as program modules, executed byone or more computers or other devices in software, firmware, hardware,or a combination thereof. The computer-executable instructions may beorganized into one or more computer-executable components or modules.Generally, program modules include, but are not limited to, routines,programs, objects, components, and data structures that perform tasks orimplement abstract data types. Aspects of the disclosure may beimplemented with any number and organization of such components ormodules. For example, aspects of the disclosure are not limited to thespecific computer-executable instructions or the specific components ormodules illustrated in the figures and described herein. Other examplesof the disclosure may include different computer-executable instructionsor components having more functionality or less functionality thanillustrated and described herein.

In examples involving a general-purpose computer, aspects of thedisclosure transform the general-purpose computer into a special-purposecomputing device when configured to execute the instructions describedherein.

The examples illustrated and described herein as well as examples notspecifically described herein but within the scope of aspects of thedisclosure constitute exemplary means for verifying contents ofcontainers on an item storage cart. For example, the elementsillustrated in FIG. 1, FIG. 2, FIG. 3, FIG. 4, FIG. 5, FIG. 6, FIG. 7,FIG. 8, FIG. 9, FIG. 10 and FIG. 11, such as when encoded to perform theoperations illustrated in FIG. 13 and FIG. 14, constitute exemplarymeans for analyzing scan data received from at least one scanner device;exemplary means for identifying an item for placement into at least onestorage container on an item storage cart; exemplary means foridentifying a selected storage container assigned to the identifieditem; exemplary means for outputting a graphical representation of alocation of the identified item on an item display within an itemselection area; exemplary means for releasing a locking mechanismassociated with the selected storage container to enable user access toat least a portion of an aperture associated with the selected storagecontainer; exemplary means for analyzing weight data generated by atleast one weight sensor associated with at least the selected storagecontainer to verify the identified item is placed into the selectedstorage container; exemplary means for re-engaging the locking mechanismassociated with the selected storage container on condition the weightdata indicates a weight increment associated with the selected storagecontainer corresponds with a known weight of the identified item; andexemplary means for outputting, by the user interface device, anotification indicating failure to detect placement of the identifieditem into the selected storage container on condition weight datagenerated by the at least one weight sensor fails to correspond to apredetermined weight of the identified item.

Other non-limiting examples provide one or more computer storage deviceshaving a first computer-executable instructions stored thereon forproviding a cart manager component. When executed by a computer, thecart manager component performs operations including analyzing sensordata to verify a correct item is placed into a correct item storagecontainer on a cart, such as a pick-cart or stocking cart; outputting anotification when an item is placed into the wrong container on the cartand/or outputting a notification when an incorrect item is placed into acontainer on the cart.

The order of execution or performance of the operations in examples ofthe disclosure illustrated and described herein is not essential, unlessotherwise specified. That is, the operations may be performed in anyorder, unless otherwise specified, and examples of the disclosure mayinclude additional or fewer operations than those disclosed herein. Forexample, it is contemplated that executing or performing an operationbefore, contemporaneously with, or after another operation is within thescope of aspects of the disclosure.

When introducing elements of aspects of the disclosure or the examplesthereof, the articles “a,” “an,” “the,” and “said” are intended to meanthat there are one or more of the elements. The terms “comprising,”“including,” and “having” are intended to be inclusive and mean thatthere may be additional elements other than the listed elements. Theterm “exemplary” is intended to mean “an example of” The phrase “one ormore of the following: A, B, and C” means “at least one of A and/or atleast one of B and/or at least one of C.”

In an exemplary embodiment, one or more of the exemplary embodimentsinclude one or more localized Internet of Things (IoT) devices andcontrollers. As a result, in an exemplary embodiment, the localized IoTdevices and controllers can perform most, if not all, of thecomputational load and associated monitoring and then later asynchronousuploading of summary data can be performed by a designated one of theIoT devices to a remote server. In this manner, the computational effortof the overall system may be reduced significantly. For example,whenever a localized monitoring allows remote transmission, secondaryutilization of controllers keeps securing data for other IoT devices andpermits periodic asynchronous uploading of the summary data to theremote server. In addition, in an exemplary embodiment, the periodicasynchronous uploading of summary data may include a key kernel indexsummary of the data as created under nominal conditions. In an exemplaryembodiment, the kernel encodes relatively recently acquired intermittentdata (“KRI”). As a result, in an exemplary embodiment, KRI includes acontinuously utilized near term source of data, but KRI may be discardeddepending upon the degree to which such KRI has any value based on localprocessing and evaluation of such KRI. In an exemplary embodiment, KRImay not even be utilized in any form if it is determined that KRI istransient and may be considered as signal noise. Furthermore, in anexemplary embodiment, the kernel rejects generic data (“KRG”) byfiltering incoming raw data using a stochastic filter that provides apredictive model of one or more future states of the system and canthereby filter out data that is not consistent with the modeled futurestates which may, for example, reflect generic background data. In anexemplary embodiment, KRG incrementally sequences all future undefinedcached kernels of data to filter out data that may reflect genericbackground data. In an exemplary embodiment, KRG incrementally sequencesall future undefined cached kernels having encoded asynchronous data tofilter out data that may reflect generic background data.
